<dinofyi-dinosaur slug="apatosaurus"></dinofyi-dinosaur>Apatosaurus, formerly known as Brontosaurus (now a separate genus), was a massive long-necked sauropod. Its tail may have been used as a whip for defense. It swallowed stones (gastroliths) to help grind plant material in its stomach.

Diet & Feeding
Apatosaurus was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.
Time Period
Apatosaurus lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.
One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
